And it depends on what you're trying to deal with: if it's occasional
brown or blackouts, or power flickers (let's not talk about Chicago, for
example), then you need enough power to provide all it will draw for a
couple minutes at most. If you're looking at longer power outages, you'll
need something a lot bigger, though one suitable for the above purpose
would usually allow it to shut down gracefully; it's not like Linux takes
a long, long time to shutdown.

Heh. Depends on your definition of "big processes", says the guy whose
users normally are running jobs that run for *days*, if not weeks.
